TILINGLSPADE.

To all 'whom it 'may concern:

Be it known that I, FRANK J. VoNDRAcEn, a citizen of the United Statesof America, residing at Cedar Rapids, in the county of Linn and State ofIowa, have invented cer tain new and useful Improvements inTiling-Spades, of which the following is a 's ecification, referencebeing had therein to t 1e accompanying drawing.

This invention relates to a tiling spade and the object thereof is toprovide a spade of such class in a manner as hereinafter set forth andclaimed with a handle that can be angularly and laterally adjusted,wit-hout the aid of a wrench or other tool, and when adjusted will beheld perfectly rigid in position.

.Further objects of the invention are to provide a tiling spade whichshall be comparatively simple in its construction and arrangement,strong, durable, efficient in its use and inexpensive to manufacture.

With the foregoing and other objects in view, the invention consists ofthe novel construction, combination and arrangement of parts ashereinafter more specifically described and illustrated in theaccompanying drawings, wherein is shown the prefer-red embodiment of theinvention, but it is to be understood that changes, variations andmodifications can be resorted to which come within the scope of theclaims hereunto appended.

In the drawings wherein like reference characters denote correspondingparts throughout the several views: Figure 1 is a perspective view of atiling spade in accordance with this invention. Fig. 2 is a perspectiveview of the handle supporting yoke. Fig. 3 is a sectional detail of thedevice illustrating a means for clamping an adjustable handle socket tothe yoke, and, Fig. 4 is a perspective view illustrating a modificationof the handle socket.

Referring to the drawings in detail, 5 denotes a semi-cylindrical bladehaving fixed to its upper face, and approximately centrally thereof avertically-disposed supporting yoke consisting of a body-portion 6 withwhich is formed integral a pair of outwardly-extending spaced flangesindicated by the reference characters 7 and 8. The body-,portion 6 is ofinverted U-shape and has each of its ends provided with a fiat extension9 having openings 10. The

extensions 9 are positioned against the inner face of the blade 5 andthrough the openings 10 extend hold-fast devices such as rivets as at 12for fixedly securing the yoke to the blade 5. The top of the bodyportion6 is provided with an oval-shaped slot 13 Vfor a purpose to be presentlyreferred to.

Referring to Fig. 1, the handle of the spade is indicated by thereference character 14 and which has its lower end extending into asocket formed by a pair of semi-cylindrical members 15 which embrace thehandle 14 and through the said members 15 as well as the handle 14project hold-fast devices 16 whereby the handle is fixedly secured tothe members 15. These latter form an element of what may be termed anadjustable handle socket forming device consisting of a quadrant shapedbody-portion 1ba slotted as at 17 and having a pair of right-angularextensions 18 which terminate at one end in the members 15. The loweredges of the extensions 18 are notched as at 19, the notches of one ofthe extensions 18 opposing the notches of the other extension and thenotches of each extension are spaced apart a suflicient distance so thatpairs of notches forming a perfect rigid connection will receive theflanges 7 and 8. The bodyportion 16a is of segment-shape and theextensions 18 conform in contour to the shape of the body-portion 16aand owing to the providing of the notches in the extensions 18, it isevident that the handle 14 can be adjusted to extend at various angleswith respect to the vertically-disposed supporting yoke. The handle 14is maintained in its adjusted position through the medium of a couplingdevice consisting of a threaded bolt 2O having its lower end formed withan enlarged head 21, the bolt 20 extends through the opening 13 and thehead 21 is adapted to engage the inner face of the bodyportion 6 of thesupporting yoke. Mounted upon the bolt 20 and above the supporting yokeis a iianged clamping member 22 which is adapted to straddle the bodyportion 16a in a manner as shown in Fig. 1. The clamping member 22 ismaintained in position by a thumb-nut 23 which is mounted upon thethreaded end of the bolt 20 and engages the clamping member 22. When thenut 23 is screwed tightly against the clamping member 22 the extensions18 are maintained in i' their adjusted position. [The opening 1 3provides` means whereby the handle may be adjusted to one side or theother orinrother words a lateral adjustment of the lhandle can be hadwith respectto the blade. Y

In'F ig. 4 is illustrated a modified form of an adjustable handlesocketforming device.`

' a socket for the reception of a handle 14 and which is provided withopenings throughwhich canextend hold-fast .devices for fixi edlysecuring the lhandle to the sleeve 24.

TheV latter has projectingfrom one end thereof -a pair'of quadrant shaped spaced arms 26 each `ofwhich is .formed on one edge withspaced notches 27 of an arrange-,mntgsimilar tothe notches 19. The arms 26 perform the same function asthe iextensions'18,. Y What I claim is `1. A tiling spade comprising ablade, a

In testimony whereof I affix my signature in the presence of twowitnesses.
